Highly recommended experience. The seal feeding is once in a lifetime. 800 yen per pax and there are only 15 slots each time.

It’s a very small aquarium and you can see it all in about 30 mins. But it does have a good range of fish and some seals. Warning: if you are using the Hakone Free Pass. There’s only one bus every hour and we got stranded as the bus was full and wouldn’t let anyone one. There’s response to well how do we get back was: get a taxi.

Small aquarium at the base of ropeway. Hundreds of types of fishes, Tiger fish, clown fish, crabs, salamander, jelly fish, turtle, and may sea creatures. There is a seal show around 15 mins. Beautiful scenery all around. There is a small shopping store with hundreds of souvenirs to take back including wooden carved paintings and special lock puzzle and candies. Small Due to high winds, ropeway may...

It's a decent small aquarium, however you can feel it's age as the aquarium definitely needs some renovation to look more modern. Price is ok, it's about 1000yen for entry so there is nothing much to complain about it. If you have gone to other Japanese aquarium this will feel small. Overall still worth seeing their seals and baby otters which are newborns and worth coming down to see them.

Our kids had great time there. But the parking fee was too expensive! When we went here last year, the parking fee was free... Anyway, the aquarium has two buildings. And the new animals "otters" were so cute. I felt their space was too small for them. But my kids were so happy to see them. They have a few show events everyday and you can enjoy. Please check their show schedules before you go!
